TOBACCO PIPE.

Application filed September 10, 1920. Serial No. 409,359.

4 Pipes, of which the following is a specification.

My invention relates to new and useful improvements in tobacco pipes,and has for its object to provide a construction wherein the entire bowlmay be made of metal the parts being so combined as to eliminate orreduce to a minimum the likelihood of the same becoming unduly heated.

Another object of the invention is to provide the air chamber about thetobacco receptacle through which a draught of, circulation will becreated by the heating of the innerwalls during the process of smoking.

A still further object of the invention is to provide a novel means forattaching the nipple to the bowl, said nipple having the mouth piececonnected therewith.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which this inventionappertains, may understand how to make and use the same, I will describeits construction in detail, referring by numerals to the accompanyingdrawing forming a part of this application, in which Fig. 1, is a planview of my pipe constructed in. accordance with my invention.

Fig. is a fragmentary sectional view thereof.

In carrying out my invention as here embodied, 2 represents the outsidecasing or bowl of the pipe stamped, molded or drawn from suitable metalsuch as brass the exterior of which may be enameled in imitation of woodand within this bowl is. set the tobacco receptacle 3.

This tobacco receptacle comprises --an inner casing 4 of metal suchas-aluminum open at its upper end to rovide for" the insertion oftobacco and t is casing has an outwardly projecting flan e 5 ada ted torest upon the 11 per edge 0 the bow 2 with a rim6 depen ing fromthe-flange and engaging the cuter face of the bowl 2 at its upper openend. The casing 4 has two different diameters so as to form an offset orshoulder 7 adjacent its upper end in which are formed a plurality ofholes 8 which act as air outlets as will be hereinafter described. Atthe lower end of the casing 4 and from the metal forming the same isproduced the depending spud 9 having a small central i opening 10therethrough through which is drawn the tobacco smoke from the tobaccocontained within the receptacle 3.

About the casing4 and spaced therefrom is an. intermediate casing 11which is also formed of metal such as brass and the upper end thereoffits over the larger portion of the casing 4 and is fastened thereto inany suitable and well known manner, while the lower end has a hole 12surrounded by an upstanding collar 18 which fits over the spud 9 and iffound desirable may be secured thereto. Because of the difl'erence insize between the small portion of the inner casing 4 and saidintermediate casing ber 14 therebetween to which air is admitted fromthe atmosphere through the vent tube 15 which is fastened in one of thewalls of the bowl 2 and one of the walls of the intermediate casing 11.?When the pipe is in use the heat from the burning tobacco within thetobacco receptacle will heat the casing 4.- and raise the temperature ofthe air within the chamber 14 causing-said air to pass upward and outthrough the holes 8 .and cause fresh cool air to pass into said its endas indicated at'17 and in this constricted end is mounted the nipple 18which snugly fits in said stem and is held against outward displacementby the ferrule 19 which has a flange. 20 for engagin the outer end ofthe nipple, saidferrule eing of such thiclmess as to lie within thedepression formed by the difference in size etween the main portion ofthe stem 16 and the major portions of the wallsvof said cas-.

mg are spaced apart and form an air chamits constricted portion. Thenipple has a threaded projection 21 formed therewith to which isdetachabl piece 22 in the ordinary well known manner, said mouth piecehaving a hole 23 therethrough which re isters with a hole 24 through thenipple an its projection.

The walls of the different elements making up the pipe being formed ofrelatively thin metal lar e air spaces are provided between the di erentparts which not only help to maintain the pipe in a cool condition, butalso assists in cooling the smoke before reaching the mouth of the userwhich is quite advantageous.

a ,When the pipe is in use the smoke will be drawn down through the hole10 inthe spud 9 and into the bowl where it will circulate about theintermediate casing 11 and reduce in temperature as it passes oilthroughthe stem ,and mouth piece and as before stated both the inner andintermediate casings 4 and 11 will be maintained relatively cool by thecirculation of air through the vent tube 15 and the chamber 14.

The large chamber in the bowl and its stem form a receptacle for anyfine pieces of tobacco, ashes or juices thatnma fall from the tobaccoreceptacle throug the hole 12 and as the hole or passageway "24 V 1through the nipple is considerably removed from the walls of the stem 16these pieces of tobacco or other foreign matter will not be drawn intothe smokers mouth but will be retaineduntil the tobacco receptacle,including the inner and outer casings, is removed and matter in the bowldislodged. The tobacco receptacle being removable, if it should beinjured or broken in may be readily replaced by a new one.

Of course I do not wish to be limited to fastened the mouth the exactdetails of construction as herein shown as these may be varied withinthe limits of the appended claims without departing from the s irit ofmy invention.

Having thus in 1y described by invention, what I claim as new and usefulis 1. A ipe comprising a metallic bowl, a metallic inner casing suported b said bowl within the same, sai casing aving an openin at itslower end and a plurality of holes adjacent its upper end, anintermediate casing surrounding said inner casing and spaced therefromto form an air chamber, and a vent tube passing through the walls ofsaid intermediate chamber and the pipe bowl to form a communlcation forthe air chamber with the atmosphere.

2. A pipe including a bowl, an inner casing supported within said bowland an intermediate casing fixed to the inner casing and spacedtherefrom throu hout portions thereof to form an air cham er, sa d innercasing having direct draught communication with the pi e bowl and saidair chamher having an 1nlet and an outlet leading directly from and tothe atmosphere independent of the pipe draught.

3. A tobacco pipe including a bowl providing a chamber, an inner casinsuspended within said bowl and provi ing a tobacco chamber in directcommunication with the bowl chamber and an intermediate casingsurrounding the inner casing within the bowl and spaced from the wallsof said inner casing and bowl to provide an intermediate air chamber forcommunication with the atmosphere at two separated points.

In testimony whereof, I have hereunto aflixed my signature.
